[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-4919 - ha singletons in heterogenous topologies

[galder.zamarreno@jboss.com]

A 3rd possibility would be to add a 2rd method to org.jboss.ha.singleton.ExtendedElectionPolicy called something like: pickSingletonIfExists() and call that from HASingletonElectionPolicyBase.isElectedMaster() if exists, otherwise call existing pickSingleton.

pickSingletonIfExists() would return null if no cluster nodes were found.
